About this service

The distribution box is a central part of your drain field system. It takes the liquid effluent from your septic tank and splits it evenly into the various pipes that lead to your absorption area. If your box gets damaged, cracked, or unevenly settled, water may pool in one part of your yard while other parts stay dry. If you see signs of uneven drainage, we can inspect your box to see if it needs repair or adjustment. Exact pricing confirmed free on the call.

Summer often means more houseguests and increased water usage, which puts extra demand on your septic tank. With more showers and laundry loads, it is easier for a tank to reach capacity. If you have guests coming over, consider a pump-out beforehand to avoid an inconvenient backup during your family gatherings.
